NEILLIA 93 



divided into two genera, viz., Neillia proper and PHYSOCARPUS. 

 The former represented in gardens by N. sinensis and N. thyrsiflora, 

 and confined in a wild state to Asia are distinguished by a racemose 

 inflorescence and a solitary, podlike, many-seeded fruit. The Physo- 

 carpus section, represented in most gardens by N. opulifolia and its 

 golden-leaved variety, has a corymbose inflorescence, and the fruit is 

 composed of two to five pods. Leaves alternate, lobed, and toothed. 

 Flowers white or pale rose. Sepals and petals five. 



In gardens this genus (named in honour of Dr Patrick Neill, a 

 prominent member of the botanical circle in Edinburgh at the beginning 

 of the nineteenth century), is chiefly known by N. opulifolia. All the 

 species are of easy culture, loving a moist loamy soil ; they are propagated 

 by cuttings of half-ripened wood. 



N. AMURENSIS, Bentham and Hooker fit. MANCHURIAN 



NINE BARK. 



(Physocarpus amurensis, Maximowicz.*) 



A deciduous shrub, 6 to 8 ft. high, the larger branches covered with a loose 

 peeling bark. Leaves three- or five-lobed, up to 4 ins. long by 3 ins. wide ; 

 more or - less downy beneath, the lobes pointed, margins double-toothed. 

 Flowers white, |- in. across, produced each on a slender downy stalk in 

 corymbs i| to 2 ins. across, terminating short twigs. Calyx with five thickly 

 downy, triangular lobes. Stamens about forty, purple ; petals downy on the 

 outside. Fruit downy. 



Native of Manchuria ; much resembling N. opulifolia. The leaves appear 

 generally to be larger, more downy beneath and more distinctly five-lobed ; 

 the downy pods too are distinctive, and much shorter in proportion to the 

 calyx. 



N. CAPITATA, Greene. WESTERN NINE BARK. 



(Spiraea opulifolia var. mollis, Torrey ; S. capitata, Pursh.~) 



A deciduous shrub, 6 to 10 ft. high (in a wild state over 20 ft.) Leaves 

 three-lobed, broadly ovate, 2 to 4 ins. long, doubly toothed, downy beneath. 

 Flowers white, produced in a corymb, each flower 'on a downy stalk about in. 

 long; calyx very downy. Fruit smooth or nearly so, composed of three to~five 

 inflated pods 1 in. long, containing usually two obliquely pear-shaped seeds. 



Native of Western N. America from British Columbia to California, where 

 it is said to have stems often more than 20 ft. long interlaced with willow 

 branches, and forming impenetrable thickets on the banks of streams (Greene). 

 It is really a western form of N. opulifolia, from which it differs chiefly in the 

 more downy leaves and in the pear-shaped seeds. Introduced in 1827. 



N. MALVACEA, Greene. 



(Bot. Mag., t. 7758 (as N. Torreyi).) 



A deciduous shrub, 3 to 5 ft. high, with erect stems. Leaves three-lobed, 

 sometimes obscurely five-lobed on the non-flowering shoots ; from i^ to 3 ins. 

 wide, scarcely so long ; usually roundish or broadly oval in general outline ; 

 variable in the amount of down on the lower surface. Flowers -i- in. wide, 

 white, produced in corymbs ii ins. wide ; calyx downy. Fruit composed of 

 two or three pods, each one- or two-seeded.
